What is the type of elements of the jagged array in C#?
A jagged array is an array of arrays, and therefore its elements are reference types and are initialized to null.
Let us see how to work with Jagged array −
Declare a jagged array −
int [][] marks;
Now, let us initialize it, wherein marks is an arrays of 5 integers −
int[][] marks = new int[][]{new int[]{ 40,57 },new int[]{ 34,55 }, new int[]{ 23,44 },new int[]{ 56, 78 }, new int[]{ 66, 79 } };Let us now see the complete example of jagged arrays in C# and learn how to implement it −
Example
using System;
namespace MyApplication {
class MyDemoClass {
static void Main(string[] args) {
int i, j;
int[][] marks = new int[][] {
new int[] {
90,
95
}, new int[] {
89,
94
}, new int[] {
78,
87
}, new int[] {
76,
68
}, new int[] {
98,
91
}
};
for (i = 0; i < 5; i++) {
for (j = 0; j < 2; j++) {
Console.WriteLine("marks[{0}][{1}] = {2}", i, j, marks[i][j]);
}
}
Console.ReadKey();
}
}
}Output
marks[0][0] = 90 marks[0][1] = 95 marks[1][0] = 89 marks[1][1] = 94 marks[2][0] = 78 marks[2][1] = 87 marks[3][0] = 76 marks[3][1] = 68 marks[4][0] = 98 marks[4][1] = 91
